Answer:
22 hours (B)
Step-by-step explanation:
John's velocity = 55mph
Sally's velocity = 65mph
John's time taken = x
Sally's time taken = x - 4
since they must cover the same distance.
and, distance = vel × time
Sally's vel × time = John's vel × time
55x = 65(x-4)
55x = 65x - 220
-10x = -220
x = 22 hours.
Therefore, Sally catches up after 22 hours
1: 1/2
2: about 1 1/2 hours

3) 180-32= 148°
4) x = 142°
5) 3x+2x = 90°
5x =90°
x= 90/5
x = 18°
6) 180 = 6x + x
180 +2 = 7x
182/7 =x
26° = x
